Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT • I. DEVELOPMENT OF THE PLAN This Stormwater Pollution Prevention Plan ("Plan" or SWPPP) was developed in accordance with the requirements of the General Permit for the Discharge of Stormwater Associated with Industrial Activities (General Permit). The permit conditions are identified as Sections 3 and 5 of the General Permit, issued on October 1, 2002, and modified July 15, 2003, by the State of Connecticut Department of Energy and Environmental Protection (CTDEEP), Bureau of Water Management. This permit has been re-issued without modification until September 30, 2010. A new permit with additional requirements takes effect on October 1, 2011. This SWPPP has been developed to address current and future permit requirements. This plan was developed for the Public Works Facility at 157 Burgess Rd.in South Windsor,CT.The facility is owned and operated by the Town of South Windsor. The Permittee for this facility is also recorded as Town of South Windsor.A copy of the site's General Permit registration form, the current DEEP General Permit, and a Site Location Map are included as Appendix A. The owner/operator/permittee supports the implementation of this SWPPP. II. STORMWATER POLLUTION PREVENTION PLAN • A. Facility Description The public works facility located at 157 Burgess Rd. South Windsor, Connecticut is approximately 40.54 acre in size.The property is bound to the north by Burgess Rd., to the east by the farm lands, to the south by power lines and woods, and to the west by woods.The facility has two building, a maintenance building which also has a office area, and a large salt shed. Town vehicles are stored mainly around the maintenance building. Stockpiles of gravel, dirt, and other materials like concrete catch basins and pipes as well as miscellaneous vehicles are stored west of the maintenance building and west of the salt shed on site.Also, a stockpile of sand is located south of the salt shed. Miscellaneous maintenance equipment like tractors and landscape trailers are stored in the old recycling center area. Employee parking is located to the north of the maintenance building. There are also multiple aboveground storage tanks (ASTs) on-site including: a de- icing AST, a heating oil AST, a waste oil AST as well as an underground storage tank(UST) located east of the maintenance building for fleet vehicles. To the far west of the site on top of the closed landfill the town performs there composting operation. One composting operation is on the west side of the landfill and the second is on the east side of the landfill. A majority of the site is covered by the facilities yard operations or the towns composting operations. The remainder of the site which are the more trafficked areas, around the salt shed and maintenance building, are covered by impervious surfaces. Multiple driveways are available from Burgess Rd.for the public works facility. All operations at this site are conducted on Monday through Friday. 1 Anchor Engineering Services, Inc.

Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT Roof Areas The roof areas of the on-site buildings are a combination of flat roofs and shallow pitched roofs to disperse rainfall. The roof area is not considered to be a likely source of pollutants. Outdoor Storage Activities Outdoor storage activities consist of the following: • Waste fluid ASTs with double-walled construction and secondary containment are located around the maintenance building. • De-icing fluid ASTs with double-walled construction and secondary containment are located around the salt shed. • Fuel/heating oil ASTs with double-walled construction and secondary containment are located around the salt shed. • Town vehicles and equipment parked outside around the maintenance building and west of the salt shed. • Dumpsters are stored outside of the maintenance building. • Stock piles of compost, sand, gravel, etc. are stored on top of the landfill and in the yard area west of the maintenance building. • Materials such as pipes, concrete catch basins, etc.are stored in the yard area. • On-site employees park their personal vehicles in parking areas to the north of the maintenance building. • Parts and additional fluids are stored in the storage sheds as well as in the maintenance building. Outdoor Manufacturing or Processing Activities =N�ooutdoor manufacturing activities are performed on-site. All maintenance and fabrication work is within the maintenance building.Compost is processed on top of the landfill. Dust or Particle Generating Processes All dust generating activities are preformed indoors. Composting of leafs on top of the landfill can create dust however, dust during this activity shall be controlled as needed. Vehicles periodically traverse the site which can potentially create dust on-site. Especially in the gravel/dirt storage areas. The areas of the site subject to vehicle travel are swept or maintained on an as needed basis. 4 Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT On-Site Disposal Practices There are no on-site disposal practices. Small amounts of MSW and waste scrap metal generated by facility workers are stored inside the building in designated containers. The MSW is transferred to an onsite covered dumpster, which is emptied as necessary by a licensed hauler.Waste scrap metal pieces area stored outside with other clean metal until a sufficient quantity is generated to allow for collection and recycling by a scrap metal contractor. Waste automotive fluids are disposed of into the on-site AST located outside the maintenance building before being disposed of off-site by licensed waste disposal contractors/recyclers. Old automotive parts are recycled as scrap metal, used batteries and old tires are recycled to specially- designated end-vendors. (iv) Spills and Leaks Per site staff and CTDEEP files, no spills and leaks of five gallons or more or petroleum products or of toxic or hazardous substances which could affect stormwater have occurred in the past 5 years at the . site. ==Asoftember 2011 no reported spills and leaks of five gallons or more of petroleum products or of zardous substances has occurred in the past 5 years at this site. E. Control Measures 1. Good Housekeeping The permittee must maintain a clean, orderly facility (e.g. sweeping at regular intervals, appropriate storage practices, proper garbage and waste management, dust control measures, etc.) in all areas that are exposed to rainfall and are potential sources of pollutants. Good housekeeping practices shall be employed by the personnel at this facility to provide a clean and orderly working environment. The goal of good general housekeeping practices is to reduce the potential for stormwater pollution from on-site activities and for spills. Employees will: • Promptly remove/remediate all spills in accordance with the level of training that they have received and immediately notify the site manager. • Police the facility for litter or debris and general cleanliness that may be inhibiting the performance of on-site drainage systems, on a weekly basis. • The outdoor area of the site that is traversed by vehicles should be swept on a as needed basis. 5 Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor,CT • Ensure all containers stored outdoors are covered when not in use and that they have drain plugs installed. • Inspections of the ASTs and UST shall be performed monthly. • Store all 55 gallon drums on secondary containment pallets indoors or in a covered area where they will not come into contact with stormwater. • Keep all facility vehicles and mechanical equipment in good repair and clean. • Conduct annual employee training so that all employees are instructed in the goals and implementation of the SWPPP. • Perform twice per year compliance inspections and routine inspection; complete associated reports and housekeeping logs. 2. Vehicle or Equipment Washing The permittee must provide, at a minimum, that no washing or rinsing of equipment, buildings or vehicles shall be allowed at the site which would allow wash or rinse waters to enter any storm drainage system or surface waters of the State without a permit. Such discharges to groundwater are not authorized by this general permit. Facility personnel wash vehicles in a the designated wash bay in the maintenance building. This discharge is directed the sanitary sewer system after being routed through an oil/water separator. fihts acility should be permitted Wider and managed m accordance with"the General Pesm9 r4tlae F17uchctrge jleb cke Mafn ten arrce �steurat�r` 3. Floor Drains The permittee must provide that all floor drains have been sealed, authorized by a local authority to discharge to sanitary sewer or allowed by DEEP in accordance with the"Non-Stormwater Discharges" section(Section 5(b)(11)) of the general permit. The wash bay is equipped with floor drains which discharges to a oil/water separator to the north of the maintenance building before being discharged to the sanitary sewer. " 4. Roof Areas The permitter must identify roof areas that may be subject to drippage, dust or particulates from exhausts or vents or other sources of pollution. The permittee must inspect such areas to determine if any potential sources of stormwater pollution are present. If so, the permittee must minimize such sources or potential sources of pollution. 6 Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT As explained earlier in this report, the roof of the facility is not considered a potential source of pollution. 5. Minimization of Exposure The permittee must minimize exposure to stormwater of materials identified in the "Inventory of Exposed Materials" section (Section 5(c)(2)(D)(ii)) of this general permit. Facilities in categories 2 and 10 of the definition of industrial activity in Section 2 of this general permit constructed after July 15, 2003 shall be constructed to preclude exposure of materials (as defined in the category 10 definition) by means of a permanent roof or cover or provide stormwater treatment, as identified in the Stormwater Quality Manual, for such exposed areas. Where the permittee believes it is not feasible to construct a permanent roof or cover, they shall submit their Plan (and plan review fee specified in Section 5(c)(4)(B)) showing the area(s) in question and reasons in writing for the commissioner's review and written approval. The permittee minimizes exposure of materials by storing various materials (oils, lubricants, etc.) indoors. All fixing, and maintenance is performed indoors. Salt is stored inside the salt shed. Routine inspecting the ASTs and UST will be preformed to minimize exposure of materials to stormwater and adequately supplying spill prevention materials near the tank in case of a spill or leak. 6. Sediment and Erosion Control The permittee must identify areas that have a potential for soil erosion due to topography, activities, or other factors, and shall implement measures to limit erosion and stabilize such areas. All construction activities on-site shall be conducted in accordance with the 2002 Connecticut Guidelines for Soil Erosion and Sediment Control (Guidelines) and the"Future Construction"section (Section 5(c)(2)(I)) of this general permit. Sediment controls include regular sweeping of the site and the on-site catch basins, and drainage swa]are The heavier trafficked areas around the site are covered with impervious surfaces so erosion controls minimal.The gravel/dirt storage areas shall be monitored and maintained for erosion. Sediment wil removed from the on-site structures annually or on an as needed basis. 7. Management of Runoff The permittee shall investigate the need for stormwater management or treatment practices that shall be used to divert, infiltrate, reuse, or treat stormwater runoff in a manner that minimizes pollutants in stormwater discharges from the site. Any evaluation, construction or modification of the design of a stormwater drainage system requires certification by a professional engineer licensed to practice in the State of Connecticut. The permittee shall implement and maintain stormwater management or treatment measures determined to be reasonable and appropriate to minimize the discharge of pollutants from the site. 7 Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT In implementing infiltration practices, care must be taken to avoid ground water contamination in accordance with Appendix C. Any stormwater infiltration measures implemented by the permittee and located within an aquifer protection area as mapped under section 22a-354b of the Connecticut General Statutes shall be conducted pursuant to sections 8(c) and 9(b) of the Aquifer Protection Regulations (section 22a-354i(1)-(10) of the Regulations of Connecticut State Agencies). The permittee must assure that stormwater run-off generated from the regulated activity is managed in a manner so as to prevent pollution of groundwater, and shall comply with all the requirements of this permit. The permittee shall consider the potential of various sources at the facility to contribute pollutants to stormwater discharges associated with industrial activity when determining reasonable and appropriate measures. Where feasible, the permittee shall divert uncontaminated run-on to avoid areas that may contribute pollutants. Other appropriate stormwater management or treatment measures may include but are not limited to: vegetative swales or buffer strips, reuse of collected stormwater (such as for process water, cooling water or as an irrigation source), treatment technologies (e.g. swirl concentrators, sand filters, etc.), snow management activities, bioretention cells, green roofs, pervious pavement and wet detention/retention basins. The permittee shall ensure that such measures are properly designed, implemented and maintained in accordance with the Stormwater Quality Manual. Runoff for the site is directed into on-site catch basins or stormwater is directed into the drainage Swale on the south side of the site. The catch basin sumps and drainage swale minimize the discharge of pollutants from the site. Most of the site is unpaved and the majority of the water on-site infiltrates into the ground. Stormwater from the paved areas on the far eastern end of the site flows to several catch basins, which drain to a drainage swale which runs along the southern border of the site. The onsite ASTs and the UST located outside are constructed with double-walled construction and have secondary containment.Should a release occur that is not containable by on-site personnel, a spill clean- up contractor as well as CT DEEP will be called. 8. Preventative Maintenance The permittee must implement a preventive maintenance program, which shall include but not be limited to: the inspection and maintenance of stormwater management devices (e.g. cleaning stormwater treatment devices, catch basins); the visual inspection and/or testing of on-site equipment and systems to identify conditions that could cause breakdowns or failures resulting in discharges of pollutants to surface waters; and the appropriate maintenance of such equipment and systems. These areas shall be included in the Routine Inspections conducted under Section 5(d)(2) of this general permit. If the permittee maintains an existing preventive maintenance program that addresses the requirements of this control measure, they may use that program to meet this requirement. The existence of such a program and the location of its maintenance records shall be referenced in the Plan. • Preventative maintenance at this site shall involve weekly visual inspections of areas which may be susceptible to spills, leaks or releases to the environment (material loading, vehicles/equipment on-site, unloading, storage, handling areas, the fan vents, and filters for the 8 Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT • building's ventilation systems) and the areas surrounding the storage areas to include all stormwater management devices (such as the on-site catch basins and drainage basin). • The catch basins shall be cleaned out on an as-needed basis. • At the end of each operating day, the facility is to be left in a clean and orderly fashion. • All dumpsters and solid waste containers shall be covered and plugs are to be installed. Containers that do not have a functioning cover or plug shall be repaired as soon as possible so as to minimize exposure of stormwater to the interior of the container. • Daily inspections include visual observations and collection of any wind-blown litter and stray materials. • All site areas and activities including material storage, maintenance, repair, and washing areas shall be informally inspected on a daily basis and formally inspected on a monthly and a semi- annual basis per the inspection form included in Appendix E. 9. Spill Prevention and Response Procedures The permittee must minimize the potential for leaks and spills. This shall include clearly identifying areas where potential spills can occur and their accompanying drainage points. The permittee must plainly label containers (e.g., "Used Oil," "Spent Solvents," "Fertilizers and Pesticides," etc.) that could be susceptible to spillage or leakage in areas that could contribute pollutants to stormwater runoff. The permittee shall identify procedures for containing, reporting and cleaning up spills. These procedures • must be provided to the appropriate personnel through Employee Training (subsection 10, below) along with the necessary equipment to implement a cleanup. A) Containment To prevent unauthorized discharges of liquid chemicals or wastewater from commingling with or polluting a facility's stormwater discharges, or otherwise causing pollution to the waters of the state, the permittee shall comply with the following requirements, as applicable: (i) Stationary Storage or Storage Areas For the purposes of Section 5(b)(9)(A) of this general permit only, storage area means an exterior area, which is or has the potential to be exposed to stormwater, that contains one or more tanks or containers utilized for the storage of liquid chemicals or for the collection, storage or treatment of wastewater. Any stationary above-ground tank, container or storage area used: (1) for the storage of liquid chemicals as identified in the "Spills and Leaks" section (Section 5(c)(2)(D)(iv)) of this general permit; or (2) for the collection, storage or treatment of wastewater shall, at a minimum,comply with one of the following types of secondary containment requirements: 1) A double-walled above-ground tank or container; or • 2) For any storage area, tank or container installed prior to the date of authorization of this general permit (Oct. 2011), an impermeable secondary containment area which will hold at least 100% of 9 Anchor Engineering Services, Inc.

(iv) Additional requirements For industrial activities initiated after October 1, 1992, if an impermeable secondary containment area is required by 5(b)(9)(A)(i) or (ii) above, such containment area shall be roofed in a manner which minimizes stormwater entry to the containment area, except for a containment area which stores tanks or containers of 100 gallon capacity or more,in which case a roof is not required. 10 Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. • South Windsor, CT Stormwater that may accumulate in a containment area may be discharged only after the permittee conducts testing to confirm that it contains none of the relevant pollutants stored therein. For petroleum storage containment areas, visual inspection for a sheen fulfills this requirement. If testing is not conducted or if it indicates the presence of a relevant pollutant, this containment water must be treated and/or disposed of according to DEEP and federal regulations. The ASTs are constructed with double-walled construction, and have secondary containment that meet the requirements listed above. The UST is constructed with double-walled construction, and is located under a concrete pad which does not allow stormwater to come in contact with the tank. B) Dumpsters The permittee must ensure that all dumpsters, trash compactors, and"roll-off' containers used to store waste or recyclable materials are in sound watertight condition and have covers and drain plugs intact, or are in roofed areas that will prevent exposure to rainfall and will not allow dumpster leakage to enter any stormwater drainage system. All covers on dumpsters not under a roof must be closed when dumpsters are not being loaded or unloaded. [All containers stored outdoors shall have their covers closed and drain plugs installed. If a containers ver does not work or if plugs cannot be installed repairs shall be performed as quickly as possible to sure these features are functioning properly. C)Loading Docks The permittee shall provide that for all industrial activities initiated after July 15, 2003, loading docks (excluding those that allow a vehicle to enter the building) shall be protected with a permanent roof or other structure that protects the loading dock from direct rainfall. Stormwater collection and drainage facilities adjacent to the loading dock shall be designed and maintained in a way that prevents any materials spilled or released at the loading dock from discharging to the storm sewer system. This site does not have a loading dock.Materials are loaded/unloaded inside the buildings as needed.A detailed list of Spill Prevention and Response Procedures is presented in Appendix H. 10. Employee Training The permittee shall ensure that all employees whose activities may affect stormwater quality receive training within ninety (90) days of employment and at least once a year thereafter to make them familiar with the components and goals of these control measures and the Plan.

A non stormwater discharge exists on-site; sewage from the on-site bathrooms, and the drains form the wash bay. The on-site bathrooms are connected to municipal sewer system and do not come into contact with stormwater. The discharge from the drains in the wash bay are collected to a oil/water separator then discharge to the municipal sewer system. The oil/water separator will be cleaned-out on an as needed basis or at least once per calendar year. Please refer to section II. F. (below) for the Non-Stormwater Discharge Certification. 12.Solid De-Icing Material Storage sThe permittee must ensure that storage piles of de-icing materials (including pure salt, salt alternatives or either of these mixed with other materials) used for deicing or other commercial or industrial purposes that are in place for more than 180 days shall be enclosed or covered by a rigid or flexible roof or other structural means. Such structure shall not allow for the migration or release of material outside of the structure through its sidewalls. As a temporary measure (not to exceed two years from the effective date of this general permit), a waterproof cover may be used to prevent exposure to precipitation (except for exposure necessary to add or remove materials from the pile) until a structure can be provided. For temporary storage piles of de-icing materials in place for less than 180 days per year, a waterproof cover may be used to prevent exposure to precipitation (except for exposure necessary to add or remove materials from the pile). In areas with a groundwater classification of GA or GAA, an impervious liner shall be utilized under any de-icing material pile to prevent infiltration to groundwater. In addition, no new road salt or de-icing materials storage facilities shall be located within a 100-year floodplain as defined and mapped for each municipality under 44 CFR 59 et seq. or within 250 feet of a well utilized for potable drinking water supply or within a Level A aquifer protection area as defined by mapping pursuant to section 22a-354c of the Connecticut General Statutes. Liquid de-icing materials (calcium chloride) are stored on site in an AST mixed with sand. The mixture is stored inside an on-site sand/salt storage shed. No solid de-icing materials are stored on site. • 13. Sector Based Control Measures 12 Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT • Section 5(0 of the general permit contains additional control measures for certain industrial activities ("sectors"). These are specific control measures that apply only to the industries in a given sector and are to be implemented in addition to the control measures in this section. Refer to Appendix H for additional sector based control measures for this facility. F. Non-Stormwater Discharge Certification "I certify that in my professional judgment, the stormwater discharge from the site consists only of stormwater, or of stormwater combined with wastewater authorized by an effective permit issued under section 22a-430 or section 22a-430b of the Connecticut General Statutes, including the provisions of this general permit, or of stormwater combined with any of the following discharges provided they do not contribute to a violation of water quality standards: • landscape irrigation or lawn watering; • uncontaminated groundwater discharges such as pumped groundwater, foundation drains, water from crawl space pumps and footing drains; • discharges of uncontaminated air conditioner or refrigeration condensate; • water sprayed for dust control or at a truck load wet-down station; • naturally occurring discharges such as rising groundwaters, uncontaminated groundwater infiltration (as defined at 40 CFR 35.2005(20)), springs, and flows from riparian habitats and wetlands. This certification is based on testing and/or evaluation of the stormwater discharge from the site. I further certify that all potential sources of non-stormwater at the site, a description of the results of any test and/or evaluation for the presence of non-stormwater discharges, the evaluation criteria or testing method used, the date of any testing and/or evaluation, and the on-site drainage points that were directly observed during the test have been described in detail in the Stormwater Pollution Prevention Plan prepared for the site.

South Windsor, CT J. Monitoring Program The monitoring program, including the requirements for collection and analysis of stormwater samples for both visual and chemical analysis, for this facility is presented in Appendix G. Base Monitoring Program Benchmarks These benchmarks apply to all permittees. Additional sector specific benchmarks that apply to the site are identified in Attachment H. Chemical Oxygen Demand(mg/1) 75 Total Oil and Grease(mg/1) 5 Sample pH 5-9 Total Suspended Solids (mg/1) 90 Total Phosphorus (mg/1) 0.40 Total Kjeldahl Nitrogen(mg/1) 2.30 Nitrate as Nitrogen(mg/1) 1.10 Total Copper(mg/1) 0.059 Total Lead(mg/1) 0.076 Total Zinc(mg/1) 0.160 Data not exceeding benchmarks After collection of 4 semiannual samples, if the average of the 4 monitoring values for any parameter does not exceed the benchmark, the monitoring requirements for that parameter have been fulfilled for the permit term. For averaging purposes for any individual sample parameter analyzed using procedures consistent with General Permit, which is determined to be less than the method detection limit, use a value of half the method detection limit reported by the analyzing laboratory. For sample values that fall between the method detection level and the reporting level (i.e., a confirmed detection but below the level that can be reliably quantified), use a value of half the reporting level reported by the analyzing laboratory. Once the benchmark for sample pH has been met and monitoring for pH has been fulfilled, the measurement of rainfall pH is no longer required. Data exceeding benchmarks Within 120 days of receiving the results of the fourth semiannual sample, if the average of the 4 semiannual monitoring values for any parameter exceeds the benchmark, the permittee must, in accordance with the Section V of this plan, review the selection,design,installation and implementation of the control measures to determine if modifications are necessary to meet the benchmarks in this permit, and either: • Make the necessary modifications to the control measures and Plan and continue semiannual monitoring until the permittee has completed 4 consecutive semiannual monitoring events for • which the average does not exceed the benchmark, or 15 Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor,CT • • Make a determination that no further pollutant reductions are technologically available and economically practicable and achievable in light of best industry practice to implement additional control measures or meet the benchmarks, in which case the permittee must continue monitoring once per year. The permittee must also document the rationale for concluding that no further pollutant reductions are achievable and submit this documentation to the commissioner for written approval. The permittee must retain all records related to this documentation with the Plan. If an exceedance of the 4 event average is mathematically certain, the permittee must review the control measures and perform any required corrective action immediately (or document why no corrective action is required), without waiting for the full 4 monitoring events, in accordance with Section V of this plan.If after modifying the control measures and conducting additional semiannual monitoring,the average of the most recent 4 monitoring events still exceeds the benchmark (or if an exceedance of the benchmark by the 4 event average is mathematically certain for the most recent 4 monitoring events), the permittee must again review the control measures and take one of the two actions above. Off-site and natural background pollutant levels Following the first 4 semiannual samples of benchmark monitoring(or sooner if the exceedance is triggered by less than 4 monitoring events),if the average concentration of a pollutant exceeds a benchmark value, and the permittee determines that exceedance of the benchmark is attributable solely to the presence of that pollutant in the natural background or in"run-on"entering from off-site, the permittee is not required to perform corrective action or additional benchmark monitoring provided all of the following conditions are met. • The average concentration of the benchmark monitoring results is less than or equal to the concentration of that pollutant in the natural background or off-site run-on; • The permittee documents and maintains with the Plan the supporting rationale for concluding that benchmark exceedances are in fact attributable solely to natural background or off-site pollutant levels.The permittee must include in the supporting rationale any data previously collected by them or others that describe the levels of natural background pollutants in the stormwater discharge; • The permittee demonstrates that the diversion of off-site run-on containing these pollutant levels is not feasible or practicable; • The permittee notifies the commissioner on the final semiannual benchmark monitoring report that the benchmark exceedances are attributable solely to natural background or off-site pollutant levels; and • The commissioner issues a written approval of the permittee's documentation demonstrating that the benchmark exceedances are attributable solely to natural background or off-site • pollutant levels. 16 Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT Natural background pollutants include those substances that are naturally occurring in rainfall, soils or groundwater. Natural background pollutants do not include legacy pollutants from earlier activity on the site. All semi-annual monitoring results must be submitted to DEEP on a Stormwater Monitoring Report (SMR) form within 90 days of the date of monitoring. K. Schedules and Procedures The permittee shall document in the Plan the schedules and procedures for implementation of control measures, monitoring and inspections. These include but are not limited to: sweeping, waste management practices and other good housekeeping measures; regular inspections, testing, maintenance, and repair of all industrial equipment and systems potentially exposed to stormwater; procedures for preventing and responding to spills and leaks; employee training; routine, semiannual and any other inspections; visual monitoring; and any quarterly, semiannual, effluent limitation and/or impaired waters monitoring.

Also,see"Toxicity Monitoring"in subsection C below. (ii) Benchmarks These benchmarks apply to all permittees. Additional benchmarks may apply to industries in specific sectors as identified in Section 5(f). Chemical Oxygen Demand(mg/1) 75 Total Oil and Grease(mg/1) 5 Sample pH 5-9 Total Suspended Solids(mg/1) 90 Total Phosphorus(mg/1) 0.40 Total Kjeldahl Nitrogen(mg/1) 2.30 Nitrate as Nitrogen(mg/1) 1.10 Total Copper(mg/1) 0.059 Total Lead(mg/1) 0.076 Total Zinc(mg/1) 0.160 The benchmarks for the parameters above(except metals) are based upon 80th percentiles of the cumulative relative frequency graphs developed from stormwater results reported under the General Permit for the Discharge of Stormwater Associated with Industrial Activity for the sampling years 2003 to 2007.Note that the benchmarks for copper,lead and zinc are based upon state Water Quality Standards and have been determined to be protective of water quality at typical dilution rates. However,regardless of the benchmarks, discharge monitoring data or other site specific information may demonstrate that a discharge is not protective of water quality. In such a case,the department may require additional measures to reduce the discharge of pollutants for any discharge specifically found to be causing or contributing to an exceedance of Water Quality Standards in the receiving water. Provided the permittee complies with all requirements of this Standard Monitoring Benchmarks subsection,exceedance of the benchmarks is not,in itself, a violation of this general permit. (iii) Data not exceeding benchmarks After collection of 4 semiannual samples,if the average of the 4 monitoring values for any parameter does not exceed the benchmark,the monitoring requirements for that parameter have been fulfilled for the permit term. For averaging purposes for any individual sample parameter analyzed using Bureau of Materials Management&Compliance Assurance DEP-PED-GP-014 31 of69 10/1/11 procedures consistent with"Test Procedures"(Section 5(e)(2)(D)),which is determined to be less than the method detection limit,use a value of half the method detection limit reported by the analyzing laboratory.For sample values that fall between the method detection level and the reporting level (i.e.,a confirmed detection but below the level that can be reliably quantified),use a value of half the reporting level reported by the analyzing laboratory. Once the benchmark for sample pH has been met and monitoring for pH has been fulfilled,the measurement of rainfall pH is no longer required. (iv) Data exceeding benchmarks Within 120 days of receiving the results of the fourth semiannual sample,if the average of the 4 semiannual monitoring values for any parameter exceeds the benchmark,the permittee must,in accordance with the"Keeping Plan Current" (Section 5(c)(5))section,review the selection,design,installation and implementation of the control measures to determine if modifications are necessary to meet the benchmarks in this permit,and either: • Make the necessary modifications to the control measures and Plan and continue semiannual monitoring until the permittee has completed 4 consecutive semiannual monitoring events for which the average does not exceed the benchmark; or • Make a determination that no further pollutant reductions are technologically available and economically practicable and achievable in light of best industry practice to implement additional control measures or meet the benchmarks,in which case the permittee must continue monitoring once per year. The permittee must also document the rationale for concluding that no further pollutant reductions are achievable and submit this documentation to the commissioner for written approval. The permittee must retain all records related to this documentation with the Plan. If an exceedance of the 4 event average is mathematically certain,the permittee must review the control measures and perform any required corrective action immediately(or document why no corrective action is required),without waiting for the full 4 monitoring events, in accordance with the"Keeping Plan Current"(Section 5(c)(5))section. If after modifying the control measures and conducting additional semiannual monitoring,the average of the most recent 4 monitoring events still exceeds the benchmark(or if an exceedance of the benchmark by the 4 event average is mathematically certain for the most recent 4 monitoring events),the permittee must again review the control measures and take one of the two actions above. (v) Off-site and natural background pollutant levels Following the first 4 semiannual samples of benchmark monitoring(or sooner if the exceedance is triggered by less than 4 monitoring events),if the average concentration of a pollutant exceeds a benchmark value,and the permittee determines that exceedance of the benchmark is attributable solely to the presence of that pollutant in the natural background or in"run-on"entering from off-site,the permittee is not required to perform corrective action or additional benchmark monitoring provided all of the following conditions are met: Bureau of Materials Management&Compliance Assurance DEP-PED-GP-014 32 of 69 10/1/11 0 The average concentration of the benchmark monitoring results is less than or equal to the concentration of that pollutant in the natural background or off-site run-on; • The permittee documents and maintains with the Plan the supporting rationale for concluding that benchmark exceedances are in fact attributable solely to natural background or off-site pollutant levels. The permittee must include in the supporting rationale any data previously collected by them or others that describe the levels of natural background pollutants in the stormwater discharge; • The permittee demonstrates that the diversion of off-site run-on containing these pollutant levels is not feasible or practicable; • The permittee notifies the commissioner on the final semiannual benchmark monitoring report that the benchmark exceedances are attributable solely to natural background or off-site pollutant levels;and • The commissioner issues a written approval of the permittee's documentation demonstrating that the benchmark exceedances are attributable solely to natural background or off-site pollutant levels. Natural background pollutants include those substances that are naturally occurring in rainfall,soils or groundwater.Natural background pollutants do not • include legacy pollutants from earlier activity on the site. (C) Toxicity Monitoring The permittee shall monitor annually for aquatic toxicity during the first two years following the date of authorization under Section 3(g)of this permit. This parameter shall be included in a regularly scheduled semiannual sample. (D) Monitoring of Discharges to Impaired Waters Industrial activities that discharge to impaired waters,as identified in Section 5(g) below,must conduct additional monitoring of discharges in addition to the requirements of subsections(A)through(C)above. (i) Discharges to Impaired Waters Without an Established Total Maximum Daily Load(TMDL) If an industrial activity discharges to an impaired water without a TMDL,the permittee must monitor annually for any indicator pollutants identified as contributing to the impairment and for which a standard analytical method exists. No monitoring is required when a waterbody's biological communities are impaired but no pollutant,including indicator or surrogate pollutants,is identified as an indicator of the impairment, or when a waterbody's impairment is related to hydrologic modifications,impaired hydrology,or temperature. This monitoring requirement does not apply after the first year of monitoring if the indicator pollutant is not detected above natural background levels,as determined by the Commissioner,in the stormwater discharge or is the result of Bureau of Materials Management&Compliance Assurance DEP-PED-GP-014 33 of 69 t 0/l/11 run-on entering from offsite and the permittee has documented that diversion of this off-site run-on is not feasible or practicable in accordance with"Off-site and natural background pollutant levels" (Section 5(e)(1)(B)(v)). In either case, the permittee must provide such documentation to the Commissioner. (ii) Discharges to Impaired Waters With an Established Total Maximum Daily Load (TMDL) For stormwater discharges to waters for which there is an established TMDL, the permittee is not required to monitor for any indicator pollutant identified in the TMDL unless informed in writing by the DEP,upon examination of the applicable TMDL and/or Waste Load Allocation(WLA),that the permittee is subject to such a requirement consistent with the assumptions of the applicable TMDL and/or WLA. DEP's notice will include specifications on which indicator pollutant to monitor and the required monitoring frequency during the first year of permit coverage. Following the first year of monitoring: • If the indicator pollutant is not detected in any of the first year samples,the permittee may discontinue further sampling,unless the TMDL has specific instructions to the contrary,in which case the permittee must follow those instructions. The permittee must keep records of this finding offite with the Plan. • If the permittee detects the presence of the indicator pollutant in the stormwater discharge for any of the samples collected in the first year,the permittee must continue monitoring annually throughout the term of this permit,unless the TMDL specifies more frequent monitoring,in which case the TMDL requirements must be followed. (E) Sector-Specific Benchmarks For those permittees conducting sector-specific additional monitoring on a quarterly or semiannual basis in accordance with a sector in"Additional Requirements for Certain Sectors"(Section 5(f)),the provisions for meeting or exceeding any sector- specific benchmarks shall follow the requirements of"Data not exceeding benchmarks"and"Data exceeding benchmarks"(Sections 5(e)(1)(B)(iii)and(iv), respectively),applying to the most recent 4 monitoring events,whether quarterly or semiannually. (F) Effluent Limitations Monitoring Certain industrial facilities are required to comply with numeric effluent limits determined by EPA as specified in"Additional Requirements for Certain Sectors" (Section 5(f)). Exceedance of any effluent limit is a violation of the general permit. Where a benchmark and an effluent limit both apply to a given parameter,the requirements to address the effluent limit exceedance supersede those of the benchmark exceedance. If the permittee exceeds an effluent limit,they must comply with the following measures: (i) Exceedance of an Effluent Limit If a stormwater discharge exceeds an effluent limit to which a facility is subject, the permittee must review the selection,design,installation and implementation Bureau of Materials Management&Compliance Assurance DEP-PED-GP-014 34 of 69 10/1/11 of the control measures and make the modifications to the control measures and Plan necessary to meet the effluent limit. The permittee must then conduct follow-up monitoring during the next qualifying rain event for any parameter which exceeded an effluent limit. (ii) Exceedance Report In addition to any reporting required after an initial effluent limit exceedance as required by Section 22a-430-30)(11)(D)of the Regulations of CT State Agencies,the permittee must submit an Exceedance Report to DEP on or before 30 days from the date the permittee receives the lab results if follow-up monitoring pursuant to subparagraph(i)above exceeds a numeric effluent limit. The report must include the following: • DEP permit number; • Facility name,physical address and location; • Name of receiving water; • Monitoring data from this and the preceding monitoring event(s); • An explanation of the measures taken and to be taken to correct the violation; and • An appropriate contact name and phone number. (2) Stormwater Monitoring Procedures (A) All samples shall be collected from discharges resulting from a storm event that • occurs at least 72 hours after any previous storm event generating a stormwater discharge. Any sample containing snow or ice melt must be identified on the Stormwater Monitoring Report form. For sites that discharge through a detention basin or other stormwater management structure,the sample shall be taken at the discharge from the basin or structure. If no discharge occurs during a monitoring period,a Stormwater Monitoring Report (SMR)form shall still be submitted in accordance with the"Reporting Requirements"section(Section 5(h)(3))of this general permit. In such a case,a notation of"no discharge"shall be made on the SMR form. Grab samples shall be used for all monitoring and shall not be combined. Collection of grab samples shall begin during the first thirty(30)minutes of a storm event discharge(flow at sampling location)and shall be completed as soon as possible. Samples shall be taken at the outfall or nearest feasible location representative of the discharge.The uncontaminated rainfall pH measurement shall also be taken,when required,at this time.All discharge samples at a facility must be taken during the same storm event, if feasible. (B) Representative Discharge When a facility has two or more outfalls that,based on a consideration of features (e.g. grass vs.pavement,slopes,catch basins vs. swales)and activities within the area drained by the outfall,the permittee reasonably believes discharge substantially identical effluents,the permittee may test the effluent of one such outfall and report that the quantitative data is representative of the substantially identical outfalls. Bureau of Materials Management&Compliance Assurance DEP-PED-GP-014 35 of69 10/1/11 The Plan shall include a narrative of the rationale for designating outfalls as representative discharges,and, for each outfall that the permittee believes is representative,an estimate of the size of the drainage area(in square feet),an estimate of the runoff coefficient of the drainage area and a description of the substantially identical activities contributing to the discharge shall be provided in the Plan. In no case shall one outfall test be substituted for more than five(5) outfalls. (C) Storm Event Information The following information shall be collected for the storm events monitored: (i) The date,discharge temperature,time of the start of the discharge,time of sampling,and magnitude(in inches)of the storm event sampled; (ii) The pH of the uncontaminated rainfall(before it contacts the ground); and (iii) The duration between the storm event sampled and the end of the most recent storm event that produced a discharge. (D) Test Procedures (i) Unless otherwise specified in this permit,all pollutant parameters shall be tested according to methods prescribed in Title 40,Code of Federal Regulations (CFR),Part 136. Laboratory analyses must be consistent with Connecticut Reasonable Confidence Protocols. (ii) Acute toxicity biomonitoring tests shall be conducted according to the procedures specified in Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms, 5th edition(EPA 82 1-R-02-012).The following specific conditions apply: • Tests shall employ neonatal(less than 24-hour-old)Daphnia pulex as test organisms; • Tests shall be conducted at 20+/- 1 degrees Centigrade; • Tests shall be forty-eight(48)hours in duration; • Synthetic freshwater prepared as described in EPA 821-R-02-012 and adjusted to a hardness of 50+/-5 mg/1 as CaCO3 shall be used as dilution water in all tests; • The sample shall not be hardness or pH adjusted or altered in any way; • The following test dilution series shall be utilized,expressed as percent stormwater sample: 100%,50%,25%, 12.5%, 6.25%and 0%; • A minimum of twenty test organisms shall be exposed to each stormwater concentration,with each test concentration containing a minimum of four (4)test chambers. Each test chamber shall contain a minimum of five(5) test organisms; • Test organisms shall not be fed during the test period; Bureau of Materials Management&Compliance Assurance DEP-PED-GP-014 36 of 69 10/1/11 • Test results shall be reported as the LC50 value determined using the procedure specified in EPA 82 1-R-02-012; • Hardness in the stormwater sample and in the dilution control water shall be reported as mg/L as CaCO3; • Toxicity tests shall be initiated within thirty-six(36)hours of stormwater sample collection; and • Any test in which the survival of test organisms is less than 90%in the combined control test vessels or failure to achieve test conditions as specified,such as maintenance of environmental controls,shall constitute an invalid test and will require stormwater resampling and retesting as soon as practicable. (E) Inability to Collect a Sample If a permittee is unable to collect a sample pursuant to"Visual Monitoring"(Section 5(e)(1)(A)(i)) or"Additional Requirements for Certain Sectors"(Section 5(f))due to the inability to meet the conditions in subsection(A)above,the permittee shall,for visual monitoring,document such inability in their Plan or,for all other monitoring, submit the Stormwater Monitoring Report form in accordance with the"Reporting Requirements"section(Section 5(h)(3))with a notation of"no discharge"and an explanation of the limitations restricting the collection of an appropriate sample. isReasons may include the absence of a 72-hour period of dry weather,the absence of a rain event that produces a stormwater discharge,the absence of a discharge from a detention or retention basin in accordance with subsection(A)above,or safety considerations preventing access to a stormwater discharge location. Timing of a rain event is not an acceptable reason to fail to sample unless it precludes the analysis of a parameter within the acceptable hold time specified by a laboratory.

The emphasis should be to minimize, to the extent possible,changes between pre- development and post-development runoff rates and volumes. The basic stormwater principals for Aquifer Protection Areas(and other groundwater drinking supply areas)are to prevent inadvertent pollution discharges/releases to the ground,while encouraging recharge of stormwater where it does not endanger groundwater quality. Measures include: • prevent illicit discharges to storm water,including fuel/chemical pollution releases to the ground. • minimize impervious coverage and disconnect large impervious areas with natural or landscape areas • direct paved surface runoff to aboveground type land treatment structures—sheet flow,surface swales, depressed grass islands,detention/retention and infiltration basins,and wet basins.These provide an opportunity for volatilization of volatile organic compounds to the extent possible before the stormwater can infiltrate into the ground. • provide necessary impervious pavement in high potential pollutant release areas. These"stormwater hot spots" include certain lands use types or storage and loading areas,fueling areas, intensive parking areas and roadways (see table below). • only use subsurface recharge structures such as dry wells, galleries,or leaching trenches,to directly infiltrate clean runoff such as rooftops,or other clean surfaces. These structures do not adequately allow for attenuation of salts,solvents,fuels or other soluble compounds in groundwater that may be contained in runoff. • restrict pavement deicing chemicals,or use an environmentally suitable substitute such as sand only,or alternative de-icing agents such as calcium chloride or calcium magnesium. Infiltration of stormwater should be restricted under the following site conditions: • Land Uses or Activities with Potential for Higher Pollutant Loads: Infiltration of stormwater from these land uses or activities(refer to Table 7-5 below), also referred to as stormwater"hotspots,"can contaminate public and private groundwater supplies. Infiltration of stormwater from these land uses or activities may be allowed by the review authority with appropriate pretreatment. Pretreatment could consist of one or a combination of the primary or secondary treatment practices described in the Stormwater Quality Manual provided that the treatment practice is designed to remove the stormwater contaminants of concern. • Subsurface Contamination: Infiltration of stormwater in areas with soil or groundwater contamination such as brownfield sites and urban redevelopment areas can mobilize contaminants. • Groundwater Supply and Wellhead Areas:Infiltration of stormwater can potentially contaminate groundwater drinking water supplies in immediate public drinking water wellhead areas.

Town of South Windsor Public Works Facility 157 Burgess Rd. • South Windsor, CT APPENDIX D Training Program and Employee Certifications • Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. • South Windsor, CT STORMWATER POLLUTION PREVENTION TRAINING PROGRAM Program Description This stormwater pollution prevention training program is instituted to provide facility employees with the information and techniques required to assure the facility stormwater pollution prevention plan (SWPPP) is properly implemented. The training programs will enable facility staff to have an improved understanding of the stormwater system and how to minimize the impact the facility has on the system. The training program consists of two components. The first aspect of the program is for employees to read the "Operational Procedures for Stormwater Pollution Prevention," which follows. The second aspect is attendance at courses for pollution prevention. The operational procedures and informational courses should be implemented and reviewed on an annual basis for all employees at the facility. Operational Procedures for Stormwater Pollution Prevention The most critical component of an SWPPP is the implementation of the plan by on-site employees. The following are some recommended operational procedures that will help reduce the amount of contaminants that enter the stormwater system: 1. Good Housekeeping Good Housekeeping refers to the general upkeep of the facility, including litter control, sweeping of roadways, spill cleanup and control, and maintaining erosion and sedimentation control devices. Good housekeeping practices should be employed by the personnel at this facility to provide a clean and orderly working environment. The goal of good housekeeping practices is to reduce the potential for stormwater pollution from on-site activities and spills. A. Litter Control Litter control is a maintenance item that, if possible, should be performed on a daily basis, or at least once/week. The facility should be walked over to assure that litter and debris is not entering or fouling any components of the stormwater management system. Cover roll-off containers stored outside when not in use and plug all drains. B. Sweeping Paved roads, drives, unloading areas (tipping floors, load out bays, truck docks), loading areas, and material storage areas should be swept periodically to remove any dirt or sand that has accumulated. Sweeping should routinely be performed once in the spring and again in late summer. Sweeping of dirt on paved surfaces greatly reduces the amount of sediment entering the stormwater system. • Any dirt and grit that enters the stormwater system and accumulates in catch basins should be removed periodically. Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT C. Maintaining Erosion and Sedimentation Control Devices Most erosion and sedimentation control devices perform their functions very well when properly maintained. However, if they are not maintained they can be largely ineffective. Maintenance of these structures consists of maintaining the integrity of the structures and the periodic removal of accumulated sediment. These structures should be inspected monthly and after each significant rain event to verify that they remain properly installed and that the quantity of entrapped sediment or debris is not impeding their performance. D. Spill Control and Cleanup Promptly remove/remediate all spills in accordance with the level of training that you have received and immediately notify the site manager. To reduce the likelihood of spills, return all chemicals and hazardous substances to their proper storage location as soon as possible, or at the end of the working day. Spill control materials are located on-site inside the building. Speedi-dry and oil absorbent pads should be kept in the inventory. There shall also be a spill kit located near the outdoor fuel storage tank. • E. Vehicle and Equipment Washing Vehicles and equipment will be washed inside the building at this facility. F. Stormwater Control Devices Properly maintain and periodically clean stormwater control devices including catch basins (sumps and inlet screens), sedimentation chamber, and drainage ditches. Stormwater control devices should be inspected quarterly and cleaned out at least once a year and as needed throughout the year. Any damage to these components should be repaired promptly. 2. Materials Handling Materials should be handled in a manner, which will reduce their potential exposure to stormwater. This potential can be reduced by the following techniques: storing hazardous materials and chemicals in a building with secondary containment; carefully handling and labeling chemicals and petroleum products; quickly and properly remediating spills; and covering materials stored outside to prevent stormwater from contacting any stored material.

South Windsor, CT APPENDIX G Monitoring Program • Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT A. Stormwater Monitoring Procedures Stormwater samples shall be collected at the drainage basin near the maintenance building and analyzed for the parameters listed above. This sampling location is noted on the Facility Site Plan in Appendix J, as DSN-001. All samples shall be collected from discharges resulting from a storm event that occurs at least 72 hours after any previous storm event generating a stormwater discharge. Any sample containing snow or ice melt must be identified on the Stormwater Monitoring Report form. If no discharge occurs during a monitoring period, a Stormwater Monitoring Report(SMR) form shall still be submitted in accordance with the "Reporting Requirements" section (Section 5(h)(3)) of this general permit. In such a case, a notation of"no discharge"shall be made on the SMR form. Grab samples shall be used for all monitoring and shall not be combined. Collection of grab samples shall begin during the first thirty (30) minutes of a storm event discharge (flow at sampling location) and shall be completed as soon as possible. Samples shall be taken at the outfall or nearest feasible location representative of the discharge. The uncontaminated rainfall pH measurement shall also be taken, when required, at this time. All discharge samples at a facility must be taken during the same storm event, if feasible. The following information shall be collected from the storm events monitored: • The date, discharge temperature, time of the start of the discharge, time of the sampling,and magnitude(in inches) of the storm event sampled • The pH of the uncontaminated rainfall(before it contacts the ground) • The duration between the storm event sampled and the end of the most recent storm event that produced a discharge. Unless otherwise specified in this permit, all pollutant parameters shall be tested according to methods prescribed in Title 40, Code of Federal Regulations (CFR), Part 136. Laboratory analyses must be consistent with Connecticut Reasonable Confidence Protocols. • Acute toxicity biomonitoring tests shall be conducted according to the procedures specified in Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms, 5th edition (EPA 821-R-02-012). The following specific conditions apply: • Tests shall employ neonatal(less than 24-hour-old) Daphnia pulex as test organisms; • Tests shall be conducted at 20 +/- 1 degrees Centigrade; • Tests shall be forty-eight(48)hours in duration; • Synthetic freshwater prepared as described in EPA 821-R-02-012 and adjusted to a hardness of 50 +/-5 mg/1 as CaCO3 shall be used as dilution water in all tests; Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor,CT • The sample shall not be hardness or pH adjusted or altered in any way; • The following test dilution series shall be utilized, expressed as percent stormwater sample: 100%, 50%, 25%, 12.5%,6.25%and 0%; • A minimum of twenty test organisms shall be exposed to each stormwater concentration, with each test concentration containing a minimum of four (4) test chambers Each test chamber shall contain a minimum of five(5) test organisms; • Test organisms shall not be fed during the test period; • Test results shall be reported as the LC50 value determined using the procedure specified in EPA 821-R-02-012; • Hardness in the stormwater sample and in the dilution control water shall be reported as mg/L as CaCO3; • Toxicity tests shall be initiated within thirty-six (36) hours of stormwater sample collection; and • Any test in which the survival of test organisms is less than 90% in the combined control test vessels or failure to achieve test conditions as specified, such as maintenance of environmental controls, shall constitute an invalid test and will require stormwater resampling and retesting as soon as practicable. If a permittee is unable to collect a sample pursuant to "Visual Monitoring" (Section 5(e)(1)(A)(i)) or "Additional Requirements for Certain Sectors"(Section 5(0) due to the inability to meet the conditions in subsection (A) above, the permittee shall, for visual monitoring, document such inability in their Plan or, for all other monitoring, submit the Stormwater Monitoring Report form in accordance with the "Reporting Requirements" section (Section 5(h)(3)) with a notation of "no discharge" and an explanation of the limitations restricting the collection of an appropriate sample. Reasons may include the absence of a 72-hour period of dry weather, the absence of a rain event that produces a stormwater discharge, the absence of a discharge from a detention or retention basin in accordance with subsection (A) above, or safety considerations preventing access to a stormwater discharge location. Timing of a rain event is not an acceptable reason to fail to sample unless it precludes the analysis of a parameter within the acceptable hold time specified by a laboratory. B. Visual Monitoring Once each quarter for the entire permit term, the permittee must collect a stormwater sample from each outfall (or a representative outfall pursuant to Section 5(e)(2)(B)) and conduct a visual assessment of each of these samples. These samples should be collected in such a manner that the samples are representative of the stormwater discharge. For monitoring purposes, quarters will begin on January 1, April 1,July 1 and October 1. The visual assessment must be made of a sample in a clean, clear glass, or plastic container, and examined in a well-lit area. The permittee must visually inspect the sample for the presence of the following water quality characteristics: • Color; 0 Odor; Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT • Clarity; • Floating solids; • Settled solids; • Suspended solids; • Foam; • Oil sheen; and • Other obvious indicators of stormwater pollution. The results of the visual monitoring will be recorded on a field data sheet and kept in Appendix B. If,based on the above indicators, the visual assessment indicates the control measures for the facility are inadequate or are not being properly operated and maintained, the permittee must review and revise the selection, design, installation and implementation of the control measures to ensure that the condition is eliminated and will not be repeated in the future. The permittee shall maintain documentation of these procedures in the Plan. C. Base Monitoring Requirements Sampling and chemical analysis of stormwater discharge at the site shall be conducted semiannually. One monitoring event shall be conducted between October 1 and March 31. The other monitoring event shall be conducted between April 1 and September 30. Monitoring events shall be separated by at least 30 days. Monitoring shall be conducted for the parameters listed below: • Chemical Oxygen Demand (mg/1) • Total Oil and Grease(mg/1) • pH (S.U.) • Total Suspended Solids (mg/1) • Total Phosphorus (mg/1) • Total Kjeldahl Nitrogen(mg/1) • Nitrate as Nitrogen(mg/1) • Total Copper(mg/1) • Total Lead(mg/1) • Total Zinc(mg/1) • Uncontaminated Rainfall pH (S.U.) Annual monitoring shall also be conducted for Aquatic Toxicity during the first two years of the permit (2011-2012 monitoring year and 2012-2013 monitoring year). D. Additional Sector Based Monitoring Requirements (Site Specific) In addition to the parameters required in "Monitoring" the permittee must sample any additional iparameters required in this subsection under the same conditions as those required in Section 5(e), unless otherwise specified in this subsection. Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT Per Section 5(f) of the General Permit, this facility falls under Sector G - Transportation and Public Works Facilities.The facility is subject to extra control measures and additional plan requirements, but is not subject to any additional monitoring requirements. E. Additional Parameters for Federal, State, or Municipal Facilities with Incidental Solid De- Icing Material Storage In addition to the general monitoring requirements, for facilities in this sector that have solid de-icing material storage on-site in conjunction with other activities, a sample shall be taken of a discharge that is representative of the quality of runoff from the deicing storage activity. Such sample shall also include the following parameters: • Chloride(mg/1) • Cyanide(mg/1) If the discharge location for this sample is already included in the facility's general monitoring program, these additional parameters may be included in that sample. Such facilities shall continue to monitor these additional parameters for the first two years of the permit term (four samples) and shall conduct visual monitoring pursuant to the requirements of "Visual Monitoring" for the entire term of the permit. The subject property is a Municipal Facility that contains liquid de-icing material storage.

South Windsor, CT APPENDIX I • Spill Prevention and Response Procedures Anchor Engineering Services, Inc. Town of South Windsor Public Works Facility 157 Burgess Rd. South Windsor, CT Spill Prevention and Response Procedures If any additional storage tanks are utilized in the future they will be stored in impermeable containment with a volume equal to the largest container, or 10%of the total container volume,whichever is larger. In the event of a spill, employees may attempt to contain the spill to prevent contaminants from entering the stormwater system. Spill control materials (e.g., speedi-dry, oil absorbent pads) are located directly adjacent to the ASTs. The team leader will be immediately contacted for directions on the proper handling of the spill. If a spill appears to be hazardous or a safety threat, then the local fire and police departments and CTDEEP should be contacted. If a spill or leak of potentially hazardous material occurs on-site the following section provides guidance as to the actions employees of the facility should take.The list of prescribed activities is generally in the order which they should be conducted. As soon as a spill is discovered by an employee, notify the facility manager. Attempt to stop the spill from entering a stormwater system (catch basins, swales, etc.). Be extremely careful in the handling of any unknown substance. The facility manager will quickly examine the spill and make a preliminary determination as to what the material is, determine if the spill will be treated as hazardous or non-hazardous, and will direct personnel to react accordingly. If the spill is determined non-hazardous, clean up the spill by utilizing proper cleanup techniques. Prepare a brief spill report for insertion into Appendix C of this document that includes, at a minimum, the following spill information: time, date, name of facility manager, employees present, type of material spilled, cause of spill, quantity of material released into the stormwater system, and a description on the procedure followed after the spill was detected. A spill report form may also need to be filed with the CTDEEP Office of Oil and Chemical Spills,which may be contacted at(860) 424-3338. If the spilled material is determined to be hazardous, or if the manager is uncertain, the manager will determine if the spill can be remediated by on-site personnel.If on-site personnel are utilized, follow the procedure in paragraph 3 above, except that the material must be handled and disposed of in accordance with state regulations for hazardous material.If the spill is in excess of the reportable quantity, as shown in Appendix C,the CTDEEP Office of Oil and Chemical Spills will be notified at(860) 424-3338. If on-site personnel are not determined to be capable of handling the spill, the facility manager will immediately contact the fire department (dial 911), CTDEEP Office of Oil and Chemical Spills (860- 424-3338), and a Connecticut licensed spill response contractor.
